The Noram Premier Stinger Clutch is one of the most popular drum clutches on the market. It's very robust with a 3-shoe design. What has separated the Stinger from other drum clutches is the drum and sprockets. Unlike most drum clutches, the drum and sprocket are two pieces rather than a solid single unit. They also use the most common bully-style sprockets. This makes the sprockets more readily available and reduces cost over clutches with specific sprocket designs or single drum sprocket clutches. Using the Bully-style sprockets helps racers use a mix of drum and disc clutches for different classes to use the same sprocket for both.
